Additionally, White Ball Cabbage pairs well with companion herbs such as chamomile, chives, mint, and thyme. 

When to Sow White Ball Cabbage Seeds 

• Outdoor Sowing: Sow seeds directly outdoors from March to May. This timing ensures cabbages can mature before the colder winter months. 
• Indoor Sowing: Start seeds indoors in late winter to get a head start on the growing season. Transplant seedlings outdoors after the last frost has passed. 

Step-by-Step Guide to Sowing White Ball Cabbage Seeds 

1. Soil Preparation: Select a sunny or partially shaded location with fertile, well-drained soil. Enrich the soil by mixing in compost or well-rotted manure to increase nutrient levels. If sowing in containers, use a high-quality compost mix.
2. Sowing the Seeds: Sow seeds in rows spaced at least 20 cm apart. Place seeds 2-3 cm apart along each row. Plant seeds at a depth of 1 cm (just below the soil surface). Cover lightly with soil and water gently. If starting indoors, sow seeds in seed trays or pots, covering lightly with fine compost. Maintain a temperature of 15-20°C for optimal germination.
3. Germination and Thinning: Seeds will germinate in 7-14 days under ideal conditions. Keep the soil moist but not waterlogged during this period. Once seedlings reach a height of 3 inches, thin them to 10 cm apart to avoid overcrowding.
4. Transplanting: When seedlings are 15 cm tall and have developed strong roots, transplant them to their final growing location. Space plants 45 cm apart to ensure each cabbage has ample room to grow and access to nutrients. Water thoroughly after transplanting to help the plants establish in their new location. 

Caring for White Ball Cabbage Plants 

• Watering: Keep the soil consistently moist, especially during dry spells. Avoid overwatering to prevent root rot. 
• Fertilising: Apply a balanced fertiliser every 4-6 weeks to encourage healthy growth. Cabbages are heavy feeders and benefit from nutrient-rich soil. 
• Weeding: Regularly remove weeds from around the plants to reduce competition for water and nutrients. 
• Pest Control: Protect young plants from slugs, snails, and caterpillars using organic methods such as copper tape or neem oil. 

Harvesting White Ball Cabbage 

• White Ball Cabbages are typically ready for harvest 90-100 days after germination. 
• Harvest when the heads are firm and reach their full size, cutting them at the base with a sharp knife. 
• For extended freshness, store harvested cabbages in a cool, dry place. Properly stored cabbages can last for several weeks.
